Skate-fastening



UNrrED STATES PATENT OFFICE.

EDWARD BRADY, OF PHILADELPHIA, PENNSYLVANIA.

SKATE-FASTENING.

Specification forming part of Letters Patent No. 83,756, dated November 3, 1868.

To all whom it may concern:

Be it known that I, EDWARD BRADY, of the city of Philadelphia, State of Pennsylvania, have invented a new and improved method of fastening skates to boots by means of a heelpiece of met-al, having a cap or cover operatin g by a spring in the cylinder to prevent dirt, &c., from clogging the stud-hole thereof, and sunk and screwed into the heels of boots, &c.

To enable others skilled in the art to which my said invention appertains to more fully understand and to make and use the same, I will proceed to further describe its construction and operation.

I form a hollow cylinder of gun-metal or other hard substance, surrounded by a similar thin plate at one end thereof, and which may be of the shape of, or a lesser size than, the heel of a boot to be screwed thereto, and the cylinder to be sunk therein, so as to attach the whole heelipiece firmly to the boot, Plate 1, Figure 1, A. Into the cylinder, the top of which is then soldered with a cover, there is inserted a spiral or other metal spring, B.

The bottom end of the cylinder is partly cut out in an oval or other equivalent shape and size to correspond with that of a stud of the ordinary kind in use on skates C.

The heel-piece is inserted in the boot in such a posit'on that the oval form of the hole therein shall be at right angles to the oval form of the stud on a skate, and the stud, being turned a quarter-way around upon the inner surface of the bottom of the cylinder, will be supported thereon,l).

A loose cover or cap is placed at the bottom of the inside of the cylinder, to be closely fitted to the sides thereof, and which will push back the spring when the stud is pressed into the cylinder a sufficient distance requisite to connect the skate to the heel-piece, and the stud partly turning around therein, E. I.

When the stud is removed to separate it from the heel-piece, the force of the .spring will press the cover back again tight against the bottom of the cylinder over the oval hole, and thus will prevent any dirt, &c., from clogging it when not attached to a skate, or if any extraneous matter should, from any cause, enter into the cylinder, the same can he readily removed and easily cleaned out, F.

The entire heel-piece, or any portion thereof, may be made of brass or any other metal, or the material, screws, &c., may be galvanized to save them from becoming rusted.

Fig. 2 shows a sectional view of a heel-piece complete when not in use and Fig. 3 is a sectional view of the same when in use, with the stud of a skate intersecting therewith.

What I claim as my invention, and desire to secure by Letters Patent, is-

A heel-piece of metal or other hard substance, surrounded at one end by a similar thin plate, which may be enlarged to the size of, and to be fastened by screws, &c., to, the heel of a boot, having a hollow cylinder sunk into the heel, containing any common spring operating against a cap covering a stud-hole, to prevent dirt, &c., from entering the cylinder, and thus to enable the stud of a skate to be adjusted to the heel of a boot without the stud-hole in the cylinder being obstructed by dirt, &c., substantially as set forth.
